The present invention has reference to the arch-.bar for cultivators gand the object thereof is to improve the construction in the severaldetailsv as will insure a perfect action of the means employed forspreading the outer ends of the drag-bars carrying the plows, sov

as to increase or diminish the distance between them without stoppingthe team, as circumstances require, and with economy of time and labor.

The invention consists in -an arch-bar for cultivators constructedsubstantially as shown in the drawings and hereinafter described andclaimed.-

Figure l of the drawings is a perspective view of my improved arch-bar,showing it applied to a cultivator, a portion ofthe cultivatoronly-being shown; Fig.. 2, a perspec tive view of the arch-bar, on anenlarged scale,

and its connections.

In the accompanying drawings, A represents one of the wheels of acultivator, B a

portion of the frame to which the wheel is g connected, and C the seatconnected to the end of the beam D, all of which may be of the usualconstruction.

The arch-bar comprises two members or depending arms E F, havingoutwardly extensions datv their lower ends, and to these extensions areconnected the ends of the drag-bars Gr H by. means of yokes I, whichembrace the ends of the drag-barsand secured thereto by meansrof boltsb. The yokes I have upwardly-extending plates c, with a plurality ofperforations d therein, with which engage curved pins upon clips f,adjustably secured to theextensions a of the arms E F by means of screwsor bolts g entering one of a series of holes hin `said extensions. Theextensions a of the depending, arms E F are provided with adjustablestops 't of any suitableconstruction secured tothe extensions -by meansof the pins j engagingthe perforations or holesh, which admit of theadjustability of said stops. The arms E F have toggle-levers J K pivotedthereto, the inner ends of said levers being pivoted together and to thebifurcated end `of a rod L, which extends upand is pivoted The hand# toan operating hand-lever M. leverM is pivoted at Z to theupwardly-extending arm m of a bracket N, and to this bracket are pivotedthe upper ends of the arms E F of the arch-bar.

The upper end of the rackebar Oconnects'with a coiled or other l suitable spring n, which spring isconnectedto the arm m ofthe bracket, and a rod o kconnects the rack-barwith a thumb-leverl p,

said lever being suitably pivoted to the operin the present instance'Ihave shown the rod o extending through an eye or opening 1' at the upperend of the rod L, and, if desired, the i end of thedrag-bar H may besupported by a l depending rodQ by the usual universal joint s, as foundpreferable.

Having no Letters Patent, isfn An arch-bar for cultivators consisting ofa bracket having upwardly-extending arm,

arms pvotally connected to the bracket and-` f having outward extensionsat their lower ends, clips adjustably connected to the ex l i tensions,the kdrag-bars, yokes adjustably' fully described myinv'ention,l I whatI claim as new, and desire to secure by yIoo 'les
